Description

CROSS REFERENCE TO RELATED APPLICATIONS This is a continuation application of PCT International Application No. PCT/JP2022/003595 filed on Jan. 31, 2022, designating the United States of America, which is based on and claims priority of Japanese Patent Application No. 2021-106664 filed on Jun. 28, 2021. The entire disclosures of the above-identified applications, including the specifications, drawings and claims are incorporated herein by reference in their entirety. FIELD The present disclosure relates to an electric power interchange method, an electric power interchange system, and a recording medium. BACKGROUND In recent years, challenges of conventional, large-scale, centralized energy systems have become more apparent, and introduction of renewable energy has expanded. Such circumstances have promoted a shift to distributed energy systems that utilize relatively small-scale, locally dispersed energy resources. For example, distributed energy resources are becoming increasingly widespread among consumers—including cogeneration, such as photovoltaic electricity generation or household fuel cells; storage batteries; electric vehicles; or negawatts (electric power saved). These distributed energy resources in homes or factories are each small in scale. Yet, a system or a concept called “virtual power plant (VPP)” is being proposed. In VPP, distributed energy resources in homes or factories are aggregated through advanced energy management technologies utilizing the Internet of Things (IoT), and controlled remotely and integrally. Thus, VPP is used to adjust the supply and demand balance of electric power and functions like a single power plant. With an electric power interchange system that uses a system such as VPP, it is contemplated to interchange electric power between two or more consumers in order to adjust the supply and demand balance of electric power. For example, Patent Literature (PTL) 1 discloses an electric power supply planning apparatus that, with the use of information about facilities where a vehicle can be charged and facilities where the electric power in the vehicle is to be used, creates a plan to move the vehicle to each of the facilities. CITATION LIST Patent Literature PTL 1: Japanese Patent No. 6541560 SUMMARY Technical Problem The technique described in PTL 1, however, has room for improvement in adjusting the supply and demand balance of electric power. Accordingly, the present disclosure provides an electric power interchange method, an electric power interchange system, and a recording medium that are each capable of further improving the supply and demand balance of electric power. Solution to Problem An electric power interchange method according to one aspect of the present disclosure is an electric power interchange method of interchanging electric power with use of a mobile body provided with a storage battery. The electric power interchange method uses a first aggregator that manages electric power supply and demand of one or more first consumers and a second aggregator that manages electric power supply and demand of one or more second consumers different from the one or more first consumers. The electric power interchange method includes: first obtaining of obtaining first information that includes electric power supply and demand conditions of each of the one or more first consumers managed by the first aggregator; second obtaining of obtaining second information that includes electric power supply and demand conditions of each of the one or more second consumers managed by the second aggregator; when a deficit or a surplus in the electric power supply and demand is detected in the one or more first consumers based on the first information, creating a moving plan of the mobile body based on the first information and the second information, the moving plan enabling electric power to be interchanged between the one or more second consumers and, among the one or more first consumers, one target consumer detected to have the deficit or the surplus; and transmitting the moving plan created. An electric power interchange system according to one aspect of the present disclosure is an electric power interchange system that interchanges electric power with use of a mobile body provided with a storage battery. The electric power interchange system using a first aggregator that manages electric power supply and demand of one or more first consumers and a second aggregator that manages electric power supply and demand of one or more second consumers different from the one or more first consumers. The electric power interchange system includes: a first obtainer that obtains first information that includes electric power supply and demand conditions of each of the one or more first consumers managed by the first aggregator; a second obtainer that obtains second information that includes electric power supply and demand conditions of each of the one or more second consumers managed
